【発明の詳細な説明】
〔産業上の利用分野〕
本発明はゴルフクラブヘッドに関するものであり、更に
詳しくは炭素繊維を主体とした強化樹脂よりなる主とし
てウッドヘッドの改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a golf club head, and more particularly to an improvement in a wood head mainly made of a reinforced resin mainly composed of carbon fibers.
従来ゴルフのウッドヘッドは柿の木を材料として造られ
たものが主流を占めていたが、柿のメタルヘッド、合成
コンポジットヘッドに取って替られつつある。Traditionally, golf wood heads were mainly made of persimmon wood, but these are being replaced by persimmon metal heads and synthetic composite heads.
合成コンポジットヘッドとしては無機質微小中空体を樹
脂と混合して成形硬化したもの（特公昭５９−８５６７
８号）或いは芯体の外殻に炭素繊維の短繊維強化樹脂を
配したもの（実開昭５２−１５８６６８号）等が知られ
ている。The synthetic composite head is made by mixing inorganic minute hollow bodies with resin and molding and hardening it (Japanese Patent Publication No. 59-8567
No. 8) or one in which short carbon fiber reinforced resin is arranged on the outer shell of the core (Utility Model Application No. 158668/1983) is known.
しかしながらゴルフヘッドに於鷺最も重要な打球面即ち
フェース面に対してはあまり注意が払われず、炭素繊維
の短繊維強化樹脂をそのまま用いるか、台形のフェース
インサートド呼ハれる板を后ではめ込む方法が一般に行
われている。However, not much attention has been paid to the most important ball-hitting surface of a golf head, that is, the face surface. Instead, short carbon fiber reinforced resin is used as is, or a trapezoidal face insert is later fitted. is commonly practiced.
ゴルフクラブヘッドに於ては打球時に打球面すなわちフ
ェース面にかかる力は非常に大きく、従来はその力に耐

はフェース面に対して平行方向にしかなく、フェース面
に対して垂直方向のつぶれに対しては何ら抵抗がないも
のであった。When a golf club head hits a ball, the force applied to the ball hitting surface, ie, the face surface, is extremely large, and conventional methods have been used to increase the thickness of the golf club head in order to withstand this force. That is, the reinforcing fibers were present only in a direction parallel to the face surface, and had no resistance to collapse in a direction perpendicular to the face surface.
本発明の目的は、かかる従来の炭素繊維を主体とした強

ップとしてのパフンスが良く特にフェース面の硬度、強

ゴルフクラブヘッドを提供することにある。The purpose of the present invention is to improve the drawbacks of the conventional golf club heads made of reinforced resin mainly composed of carbon fibers, to provide good puffiness as a tap, and especially to have high hardness and strength on the face surface, and to improve the hardness and strength of the face surface when hitting the ball. The objective is to provide a smaller golf club head.
即ち本発明の要旨とする所は、芯体がガラスバルーンと
樹脂、外殻が炭素繊維を主体とした強化樹脂とから成る
ゴルフクラブヘッドに於て、少くともフェース面全体に
配された、１ｍｍ以上の厚さを有する炭素繊維を主体と
した三次元織物及び外殻を形成する他の炭素繊維を主体
とした強化樹脂とを一体成形して成るゴルフタップヘッ
ドにある。That is, the gist of the present invention is to provide a golf club head in which the core body is made of a glass balloon and resin, and the outer shell is made of a reinforced resin mainly made of carbon fiber. This golf tap head is formed by integrally molding a three-dimensional fabric mainly made of carbon fibers having the above thickness and a reinforced resin mainly made of other carbon fibers forming an outer shell.
本発明は炭素繊維を主体とする三次元の織物をフェース
面の全体に配するものであ〕、三次元の織物としては厚
みが、１ｍｍ、１ｍｍ１以上、８ｍ以下であシ、好まし
くは２−以上７ｍ以下である。In the present invention, a three-dimensional woven fabric mainly composed of carbon fibers is arranged over the entire face surface. 7m or less.
厚みが１■未満では三次元織物の効果がなく、特に外層
に配した場合にはスコアツインを入れた場合にほとんど
切断されてしまう為好ましくない。又８■を越えると成
形が困難になると同時に、硬くなシすぎる為フィーリン
グが悪くなってしまう為好ましくない。If the thickness is less than 1 inch, the three-dimensional fabric will not be effective, and especially if it is placed on the outer layer, most of the score twins will be cut when inserted, which is not preferable. Moreover, if it exceeds 8■, it is not preferable because it becomes difficult to mold and at the same time, the feeling becomes poor because it is too hard.
使用する三次元織物は炭素繊維を主体とするものが好ま
しいが全体の５０ ｗｔ’１未満の範囲で他の繊維を混
入しても差支えない。The three-dimensional fabric used is preferably one mainly composed of carbon fibers, but other fibers may be mixed in the total amount of less than 50 wt'1.
使用する三次元の織物は、フェース面に垂直方向（第一
図の２方向）の繊維量が全体の３４以上３５優坂下の物
が好ましく、３４以下ではフェース面に垂直な方向の抵
抗が少く、３５憾を越えるとフェース面全体の剛性のパ
フンスが悪くなる。The three-dimensional fabric to be used preferably has a total fiber content of 34 or more and 35 or less in the direction perpendicular to the face surface (two directions in Figure 1); if it is less than 34, the resistance in the direction perpendicular to the face surface is small. , 35, the stiffness of the entire face surface deteriorates.
更にこの三次元の織物をフェース面に配するに際してフ
ェース面全体に本体と一体成形する事が必要である。Furthermore, when placing this three-dimensional fabric on the face surface, it is necessary to integrally mold the entire face surface with the main body.
三次元の織物をフェース面に配し充分な効果を発揮させ
る為にはフェース面全面に配すると同時に本体と一体成
形する事により、ボーμがフェース面のどこに当っても
、全体で力を受ける事が出来るようにする事が可能とな

達する事が可能となり、従来よシフ４以上飛距離を伸ば
す事が可能となる。従来のヘッドではフェースの打球部
分で凹みが起り、プ・ルフヘッドスピードの力を効率良
くポーμに伝達する事が出来ないのである。In order to achieve the full effect of arranging a three-dimensional fabric on the face, it is placed over the entire face and at the same time is molded integrally with the main body, so no matter where on the face the ball hits, the entire ball receives force. This makes it possible to efficiently transmit the force of the golf head speed to the ball, making it possible to extend the flight distance by more than 4 shifts compared to conventional golf balls. With conventional heads, a dent occurs in the ball-hitting part of the face, making it impossible to efficiently transmit the force of the golf head speed to the ball.
更に言えば本発明に使用する三次元の織物の成形品の垂
直方向（第１図の２方向）の剛性は垂直方向に繊維が配

通常は５０４以上高いのであシ、これが優れた特性を撥
揮する源となっているのである。Furthermore, the rigidity of the three-dimensional fabric molded product used in the present invention in the vertical direction (two directions in Figure 1) is at least 354 or more compared to conventional molded products because the fibers are arranged in the vertical direction.
It is usually higher than 504, which is the source of its excellent repellency.
次に本発明を更に具体的に説明する。Next, the present invention will be explained in more detail.

適当な方法により賦型硬化させたものを準備する。First, the stones are made by kneading glass balloons (hollow spherules) with epoxy resin, unsaturated polyester resin, vinyl ester resin, etc. and molding and hardening them using an appropriate method so that the density is (L3 ~ α817 cm). prepare.
これに必要とされる特性は全体の重量を出す為の密度と

The impregnated material is set on the face so that it becomes ~70%. It is preferable that the reinforcing fibers of the random EIMO and woven SMO fibers are mainly carbon fibers so that the entire face is 5 to 10-, but other fibers may be mixed within the range of less than 50wt4. do not have.

。Further, it is preferable to use the same resin as the three-dimensional fabric for the random BMO and woven fabric 8MCI used here, but it is not necessarily necessary to use the same resin as long as it can be molded simultaneously.
外殻の他の部分についてもおおむね肉厚が１゜−以上と
なる様にランダム８Ｍ０１織物ＥＩＭＯ等を充填する。Other parts of the outer shell are also filled with random 8M01 woven EIMO or the like so that the wall thickness is approximately 1° or more.
三次元織物はフェース面の最外層に配する事が好ましい
が、フェース面であれば内層に配しても充分効果が得ら
れるものである。It is preferable to place the three-dimensional fabric on the outermost layer of the face, but sufficient effects can be obtained even if the three-dimensional fabric is placed on the inner layer of the face.
ここで使用するランダムＳＭＯ，織物ＥＩＭＯは炭素繊
維を主体とすることが好しく ５ Ｑ ｗｔ４未満の範
囲で他の繊維を混ぜることは差支えない。It is preferable that the random SMO and woven EIMO used here are mainly composed of carbon fibers, and other fibers may be mixed within a range of less than 5 Q wt4.
